San Antonio ISD is canceling seven football scrimmages as a precaution among rising numbers of coronavirus cases. District officials made the announcement on Wednesday. They said the idea is to remove competition against teams outside SAISD prior to the start of the season, and to give student-athletes more time to be vaccinated. That way, district officials hope their teams' regular seasons will be able to proceed as scheduled. SAISD is the first local school district to change its preseason plans this year because of the pandemic.
